im wondering which dungeons are the biggest in the whole of skyrim. black reach where you get crimson nirnroot is obviously one and im guessing the dragopriest one's and labirinthian are big but i am wondering which other ones are huge and are fun to explore. cheers

nothing comes close to the Black Marsh.

However a lot of dwemer ruins do seem to go on forever.

I'd say Blackreach. It's almost just another world of its own just because of how big it is. It even has elevators that take you to the Dwemer ruins that have an entrance to the place. That place is almost overkill in how big it is.

The Forgotten Vale is huge. The wiki says it's about 2x or 3x bigger than Blackreach.

Labyrinthian is pretty damn huge. I don't know how it stacks up to Blackreach and those other places though.

Blackreach since it has all those dwemer ruins connected to it.

Blackreach is amazing!



...Black Marsh?
